Fig. 1 gives and have been shown general structure of the present utility model, in shell block (24) design and installation comprise line Clamp down on mechanism, tension force wheel mechanism, lever (44), yarn guiding wheel (28), tension force overload time-delay switch (25), the tension force o controller of broken yarn self-stop switch (34) composition. Describe below in conjunction with Fig. 2 Line is clamped down on mechanism, and the press nips (22) of clamping down on line is placed in the pinch roller seat (17) press nips (2 2) be fixing wheel (15) under, pinch roller seat (17) forms knot with the sliding bar of pressure (18) Component can slide up and down along two guide wheels (14), be equipped with on the sliding bar of pressure (18) stage clip (21), Centring ring (20) and adjusting nut (19), adjusting nut (19) is spiral shell with shell block (24) Line connects, and by up-down adjustment, can obtain the suitable power of clamping down on of line. Fixing wheel (15) below is little power What slide bar (10) and damping brake shoe (16) composition forms with it unsteady the contact in conjunction with part, the sliding bar of little power (10) upper cover has centring ring (12), little spring (9) of defeating, the sliding bar (10) of little power and below Master control bar (4) upper end in the hole form and be slidingly matched, be equipped with on the master control bar (4) master control stage clip (8), Centring ring (7), adjusting nut (5) and be fixed on nut support seat (6) on the shell block (24), Slip supporting base (3), lower end is connected with hinge seat (1), and (1) two side of hinge seat has length Square tube hole e cooperates by hinge pin (2) with an end of lever (44), forms slide hinged. By little The tension fluctuation of power spring (9) control line by the effect of lever (44), changes master control bar (4) About, can change damping brake shoe (16) to the damping of fixing wheel (15), thus adjust suitable Clamp down on power; Lever (44) two ends have slotted hole a and b, are installed in by supporting shaft (43) The slotted hole c of shell block (24) upper (Fig. 5), in order to the adjustment (adjusting) lever ratio, an end of lever (44) With hinge pin (2) form slide hinged, the other end by hinge pin (40) form slide hinged with Tension force wheel drop shot (38) links to each other. In conjunction with Fig. 3 the tension force wheel mechanism is described, upper slide bar (33), lower Sliding bar (38), tension force wheel seat (36) are in conjunction with part, and tension force wheel (35) is by bearing pin (42) Be fixed on the wheel seat (36), have on the upper slide bar (33) stage clip (32), centring ring (31), Adjusting nut (26) is fixed on the shell block (24) drop shot by nut support seat (27) (38) be fixed on the shell block (24) by slip supporting base (37), its lower end and hinge seat ( 39) connect (39) two rectangular through hole f of side opening of hinge seat, the front and back of hinge seat (39) Have rectangular through hole d, relative two sliding posts (41) are arranged in that rectangular through hole is in-built; The centre be lever ( 44) the other end connects two sliding posts (41) and lever (44) by hinge pin (40) Be connected into slide hinged. When upper drop shot (33), (38) move downward stroke when big, because sliding Post (41) stroke in rectangular through hole d is bigger, can idle running occur and breaks away from lever (44) effect. The bearing pin (30) of guide roller (28) is installed on shell block (24) upper (Fig. 4), guarantees the suitable of line Sharp output. Tension force overload time-delay switch (25) is installed on the upper right side of upper slide bar (33), tension force mistake When carrying, tension force wheel (35) rises sliding bar (33) and presses to time-delay switch (25), pass through switch (25) delay control circuit in, delayed shutdown when guaranteeing the tension force overload; Disconnection self-stopping switch (34) Be installed on the shell block (24) of lower right side of tension force wheel seat (36), during broken string, tension force wheel seat (3 6) move downward, under the effect of stage clip (32), the lug of tension force wheel seat (36) is pressed onto broken string Automatic stop switch (34), Main Engine Cut-Off.

Embodiment: the use before weaving is knitted on the warping

The arrangement of universal adjustable constant tension o controller is installed on coil holder, and yarn is introduced warping machines from input insulator (11) through fast pulley (15), straining pulley (35), guide roller (28), output insulator (29).Adjusting nut (19) makes yarn obtain suitable static state between press nips (22) and fast pulley (15) and clamps down on power; Warping machines when work, yarn by straining pulley (35), from yarn guiding wheel (28) when insulator (29) export, under by the tong-like attitude, lifting straining pulley upper and lower slide bar (33,38) stage clips (32) reach the tension force setting very soon; Effect by lever (44), can cause clamping down on the motion change of mechanism's master control bar (4) and little power slide bar (10), when yarn is influenced by initial tension and other extraneous factor, tension force can fluctuate, when yarn input tension force is bigger than normal, the upper and lower slide bar of straining pulley (33,38) moves upward, pull lever (44), master control bar (4) is moved downward, little spring (9) of defeating reduces gradually to the pressure of damping brake shoe (16), thereby reduced the power of clamping down on, the tension force trend setting of yarn to the kinetic damping and the yarn of fast pulley (15); When yarn output tension force is less than normal, the upper and lower slide bar of straining pulley (33,38) is under the effect of stage clip (32), to lower slider, though hinge seat (39) has an idle running, but be not enough to break away from the effect of lever (44), master control bar (4) is upwards slided by the effect of master control stage clip (8), and lever (44) one ends make progress, and the other end is downward, little spring (9) of defeating is compressed, increased the kinetic damping of damping brake shoe (16) to fast pulley (15), yarn is clamped down on power and is just risen, and output tension force tends to setting again.Like this, whole tension control mechanism has been set up dynamic equilibrium, defeats the interference that spring (9) is eliminated ectocines such as initial tension by little, has realized the purpose of the permanent tension force output of yarn.Slide bar (33,38) to lower slider, is crossed the idle running of hinge seat (39) about during broken yarn under the effect of stage clip (32), and the lug of tension force wheel seat (36) is depressed into the broken string Automatic stop switch, makes Main Engine Cut-Off; When the tension force overload takes place, yarn draws high straining pulley (35), make upwards top of upper slide bar (33), contact tension force overload delay switch (25) is not because delay function can cause stopping to yarn instantaneous overload tension pulse, reduce misoperation, improved work efficiency, when the time-delay overload arrived setting-up time, main frame just can stop.

When reeling machine stops the back startup, owing to tension force stage clip (32), master control stage clip (8), little acting in conjunction of defeating spring (9) and lever (44), the pulse of tension force can not appear, can compensate the tension force of yarn effectively, reach permanent tension force output.

The utility model, reasonable in design, structure optimization can be fit to different yarns and net wovenly make with line Tension force control, highly versatile, and have disconnection self-stopping, tension force overload time-delay control, permanent tension force output etc. are excellent The point.
